Hi All
Took Bugeye #1 out for its first extended run since completion of the engine
rebuild. All driving to this point had been limited to runs of a couple of
miles or so for tweaking purposes and oil leak checks. Total run ended up
being about 50 miles. The rest of the club went the full 90 or so. The good
news is that the engine ran great.....Most of the time. The bad news is that 6
or 7 times during this 50 or so miles, always while cruising at a constant
speed (about 60), the engine would start to miss sounding like a plug wire had
come off. The first time I stopped to check the plug wires and by the time I
stopped it was running fine again. If I kept driving it would go for a minute
or two (one time it kept up until I slowed down and pulled over but didn't
stop) and then start running o.k. again for a few miles. Every time I stopped
it would be running perfect. I finally gave up and took it home. Pulled the
plugs and they looked o.k., kind of a light tan on the electrode, not wet or
oily, but then it was running well for the last three miles. Pulled the
in-line fuel filter and it seemed o.k. but replaced it anyway. The car has a
new gastank and new fuel lines except for the metal portion that runs from the
tank to the engine bay and it was blown out prior to installation of the tank.
Plug wires, points, condenser, and cap are all new as is the coil. It also
has a new downdraft Webber. I have never messed with a Webber before and it
appears that there is only one adjustment screw besides the idle speed
adjustment. The carb did not come with any instructions on adjustments and
have not got around to finding a good book on the subject. I just tweaked it
to where it seemed to idle the best. Any ideas? Any recommendation on the
Webber book to buy? Could the carb be jetted wrong? These things are sold
with the 1275 in mind so does the 948 require a larger needle to provide less
fuel? How about a pressure regulator, should the Weber have one, could the
fuel pump (new electric) be providing too much pressure? I have a feeling
this is going to be a tough one because it requires a fairly long run to
determine if any mods made a difference. Any and all comments will be greatly
appreciated. This has not been a good week for Spridgets in the Miller
garage.
